This question is highly arguable. I would look to notes/book for specific answer to answer this without argument, but you can argue a lot. Most of this region is Pierre Shale. Though "Top layer" would equate to soil, which is ambiguous. it is a mixture of Pierre shale detritus and organic material (what makes it essentially soil)... (if this is intro Geology this is still true, but look to your book for the answer because they don't want the real one). Soil, is not dirt, which is not detritus. If I haven't helped, Google those 3 and you can argue your case if it comes to that.

Get a litre of milk. Drink it. Cut off the top of the bottle. Measure the bottle. Write it down. Fill ithe bottle with soil. Measure it. Take of the the empty bottle's weight from this weight. Multiply it by 100. Cheers, Szoroshun

What exposed the soil of the gret plains?
The Great Plains were exposed when the glaciers retreated at the end of the last ice age. As the glaciers melted they left behind deposits of silt and rocks. This exposed the soil of the Great Plains which is composed of two distinct layers. The top layer is composed of a mix of clay sand and silt that is generally well-drained. The bottom layer is composed of a mix of clay silt and sand and is much less permeable. This combination of layers has allowed for the development of a unique ecosystem in the Great Plains.The exposure of the soil on the Great Plains was also a result of human activities. Europeans began to settle the area in the 1800s and began to plow the land. This process exposed the soil making it easier to plant crops. As the population of the Great Plains grew more and more land was plowed further exposing the soil.Overall the soil of the Great Plains was exposed due to a combination of natural forces and human activities. The glaciers melting at the end of the ice age left behind deposits of silt and rocks while human activities such as plowing the land further exposed the soil. This combination of forces has allowed for the development of a unique ecosystem in the Great Plains.
